In this paper, condition monitoring of the internal parts of a radial active magnetic bearing (AMB) system is performed by means of Cepstrum analysis, Wigner-Ville Distributions (WVD) and enveloped Equi-Sampled Discrete Fourier transforms (ESDFT). Sensor faults, power amplifier failures and controller faults were induced in both the simulation and physical AMB system. Condition monitoring by means of the abovementioned techniques were then performed on the displacement and current signals of the simulation and physical AMB system. Results were compared and conclusions were made on how effective Cepstrum analysis, WVD and enveloped ESDFT were on the faults induced on the AMB system.
